Shin Sedai Robot Senki - Brave Saga

Emperor Grandark dispatches forces toward Earth. At the VARS Stadium, Shunpei and his best friend Hiro have made it to the championship finals. Two Geist-stars attack the stadium before the match can be held. Fribird and Exkaiser move to hold them off while Shunpei wakes up inside a burning arena to find Hiro buried under rubble. Believing his friend dead, Shunpei starts to cry — and his VARS device speaks, introducing itself as Sei Yuusha Ban, a Star Hero who needs Shunpei's help against the forces attacking Earth. Shunpei refuses until a classmate named Nanako is about to be crushed by falling debris. The adventure begins.
